Here is a great choice for a new build or to upgrade any modern sporting rifle. The Wisconsin Trigger Milazzo-Krieger MKIIA3B 2 stage match grade trigger is easy to install and tune. Featuring the Bronze Advantage and ambidextrous installation, you can choose which side to put the safety paddle on. It shares all the same features as the A2 model including the redesigned disconnector, this trigger has a short hammer reset and adjustable second stage release. The trigger fits any standard small pin AR-15 platform.
The Bronze advantage gives you, added lubrication retention while less lubrication is required. It provides less trigger friction, less pin wear and less trunnion hole deflection. This means a longer life and less risk of malfunction in your trigger group.
